FASST: Hybrid FH/DSSS channel shifting system, it will scan the band at boot and has error checking and correction capabilities.

You are fooling yourself if you think a cheaper system is going to have the same performance. There is a reason the stay with the FASST system. Quite frankly I believe we will see people losing aircraft just as I have seen with the TATIC system and with other simple FHSS systems.

What bugs me about Futaba putting out this "cheaper" system is that FrSky and Corona can put out 8 and 14 channel FASST compatible RXs for $30. Futaba is selling the same thing for up to $200. Seems that even that is not enough profit for them.

One airplane working ok is not the same as thousands of flights with NO hiccups. I have probably 2000-3000 flights on the FASST system with no anomalies. With one of the first DX7s I lost 6 aircraft in 300 flights. A friend tried the Tatic (Anylink) system and started out having the similar results as the DMS DX7. Tried it with a 12Z and an 8FG. Bad in all cases. I would rather fly an OrangeRX FASST RX anytime over any of the DSM, DSM2, FHSS, or Tactic systems.

BTW "Anylink" was a great advertising ploy. That module is just the same as using a Xtremelink, FASST, Spectrum, FRSky, etc. module in any radio with a module bay. It does NOT work with anything but TATIC receivers, just as the rest of them only work with their own system. "Anylink" is the name NOT the function.

Futaba has to account for the development costs, where the Chinese clones do not. They simply "copied" (nice way to say "stole") the technology.

To paraphrse you "If you think the cheap Chinese clones are as good as the genuine Futaba FASST receivers, then you're fooling yourself".

Back in the '60's I remember when Futaba came out with their digital systems. It was a copy of the systems developed here in the states.

Status: offline 		Youwill never convince the 'big spenders" that their choice is not demonstrably superior.
I fly with guys using the top price stuff - - can I see find any real advantages over other stuff?
programming is awkward to me - but the transmitters are very pretty tho way too heavy for my tastes
When it come to " no glitches"
No advantage seen yet -
If it makes the guys happy - then it is the right choice .
Reminds me of buyers trying to demonstrate superiority of some grossly overpriced German cars vs Honda/Hyundai and Toyota .
It's just sizzle with little steak.

Status: offline 		Favorite is DX8- tho I have the DX18 -very complete capabilities
The lighter DX8 is simply the most handy. Also have some JR stuff -seldom used now
No problems and easy to use.
Big planes, little planes - all work nicely. The new moderate priced Futabas I see appear to perform every bit as well as the higher priced ones .
It's all a matterof choice -I don't see any "superior" signal tho.

It sounds like you are saying the 2.4 GHz systems are really no better than 72 MHz systems.
